Description

Technical Field

[0001] The present invention belongs to the field of cosmetic technology, and specifically relates to a men's skin care composition and a preparation method and application thereof. Background Technology

[0002] Studies have shown that there are significant differences between male and female skin. Affected by hormones, lifestyle, environment and other factors, male skin problems are becoming increasingly prominent. The main characteristics of male skin are vigorous sebum secretion, thick stratum corneum, low skin pH and high hair density. This is because men have higher androgen levels, which leads to vigorous secretion of sebaceous glands and more skin oil, resulting in large pores, blackheads, acne and other problems. The stratum corneum of male skin is about 20%-30% thicker than that of female skin, and the skin barrier function is stronger, but it is also more prone to roughness and dullness. In addition, the pH value of male skin is lower, acidic, and easy to breed bacteria. Men have more facial hair and shave more frequently, which can easily lead to skin barrier damage, skin sensitivity and irritation, redness, swelling, folliculitis and other problems. In recent years, men's skin care awareness has gradually improved, but it is still lower than that of women overall, and their skin care habits are irregular. Men's cleaning products have strong cleaning and degreasing power, and excessive cleaning may damage the skin barrier. The use rate of after-shave care products is low, leading to skin irritation problems. Men do not pay enough attention to oil control and acne treatment, which leads to oily and rough skin. Men prefer simple and efficient skin care products and pay attention to the user experience. Therefore, men's skin care products need to have multiple functions such as oil control, acne treatment, soothing, and repairing.

[0003] CN114762669A discloses a men's oil control composition and its preparation method and application. The raw materials include, by weight: 0.2-1 parts of hornbeam plant extract, 0.1-1.5 parts of amino acids and their derivatives, 0.5-2.5 parts of skin regulators, and 80-120 parts of solvents. The oil control composition of the invention is compounded with mahogany seed extract and sarcosine. Based on the characteristics of men's skin, it blocks the IGF-1 signaling pathway and inhibits the synthesis of 5α-reductase, thereby inhibiting the proliferation of sebaceous gland cells, regulating the normal differentiation of sebaceous gland cells, reducing the activity of sebaceous glands, reducing sebum secretion, and improving the oily phenomenon.

[0004] CN108014045A discloses a men's skin care composition and its application. The invented men's skin care composition comprises the following components by weight: 2-6 parts of rocket leaf extract, 1-5 parts of plum fruit extract, 1-3 parts of medicinal pore fungus extract, and 2-10 parts of water shield leaf extract. The invented men's skin care composition can be used in men's skin care products, and has multiple effects such as efficient moisturizing, oil control, anti-aging, anti-pollution, prevention of skin sensitivity and inflammation, and the men's skin care products of the present invention can be made into skin care towels. Just wipe it gently on the face to achieve multiple skin care effects, and it has the advantages of easy use and significant effects.

[0005] However, the above-mentioned cleaning products for men have too strong cleaning power. Although they can effectively remove facial oil and effectively control oil, excessive cleaning may cause damage to the skin barrier and cause sensitive problems, or the oil control effect is not long-lasting. If it only removes oil through surfactants, the oil control effect is mostly short-term and cannot regulate sebum secretion for a long time. Therefore, it is urgent to provide a product for men with more significant, comprehensive and long-lasting effects to meet application needs. SUMMARY OF THE INVENTION

[0006] In view of the deficiencies of the prior art, the present invention provides a men's skin care composition and a preparation method and application thereof.

[0148] 5.2. Qualified subjects should use alkaline soap products to clean their faces under the guidance of staff, and then wipe them clean with a dry, absorbent paper towel. Sit quietly in a room that meets the requirements for at least 30 minutes, and do not drink water or beverages during this period.

[0149] 5.3. At each visit, the dermatologist will evaluate the acne on the face of the subject using ISGA score and count the facial acne. The ISGA score is the degree of acne skin lesions, which is divided into 0 to 5 levels. The higher the level, the more severe the acne skin lesions.

[0150] 5.4. Use a skin image analyzer to take frontal face images / left face images / right face images. Use image analysis software to analyze the number of blackheads, acne red area ratio and pore area ratio of the skin in the test area.

[0151] 5.5. At each visit time point, the skin epidermal oil content tester (Sebumeter®SM815) was used to measure the skin oil content. The test was performed three times and the average value was taken.

[0152] 5.6. At each visit time point, use a skin moisture tester (Corneometer® CM825) to measure the moisture content of the stratum corneum of the skin. Test three times and take the average value.

[0153] 5.7. The staff will distribute the test products to the subjects and provide product instructions to clarify the use of the products (including the use site, method of use, amount used each time, frequency of use, precautions, etc.) to ensure that the subjects use the products correctly and continuously until the end of the test cycle.

[0154] 5.8. The subjects returned to the laboratory at the set time point and conducted questionnaire surveys and tests according to steps 5.2-5.6 under the same experimental conditions. This experiment set two test points (D0 and D7), and the entire test cycle was 1 week.

[0155] 5.9. During the follow-up visit, the subjects need to bring the test products back and fill out the product satisfaction questionnaire.

[0156] 5.10. If the subject has any adverse skin reaction during product use, the test should be terminated immediately and the subject should be given appropriate medical treatment. Adverse reactions should be recorded.
